When my sons got interested in surfing - before they started, I took them out to the beach in Destin a few days and showed them how to spot the undertow - and USE it to help them get out past the break.
Told them before they surf - they need to sit and study the beach for a few minutes. Find the better breaks. Note the undertow, and of course if they lost their board - to never fight the undertow - swim to the right or left to leave the "trough," - and THEN make your way back in.
We lose folks here every Summer. Sometimes kids, too often parents, and others who have no idea of what's UNDER the surface, and then try to swim against it - thinking the shortest distance is straight between two points.
I'm not in charge, but every tourist prior to checking in - should be required to watch a two or three minute video to show them the dangers, how to spot the undertow, how it works, and how to calmly swim out of it.
And if they're color blind. Red flags are bad. Double red flags are worser. No no's.
Unless the family is in the mood for a funeral.
What a waste.
